An optical device, generally referred to as an intraocular lens (IOL), intended to be implanted permanently in the posterior chamber of the eye (ring-like space filled with aqueous humor between the iris, the crystalline lens, and the ciliary body) to replace the natural lens (crystalline lens), typically because it has been clouded by a cataract. The device is made of a synthetic material (e.g., plastic, hydrogel). Included may be a sterile, single-use, IOL injector into which this device is preloaded and ready for insertion into the eye.
